Using Electricity. Study Guide. Unit I2. ZIM-SCI, Zimbabwe Secondary School Science Project. Year 2.

The Zimbabwe Secondary School Science Project (ZIM-SCI) developed student study guides, corresponding teaching guides, and science kits for a low-cost science course which could be taught during the first 2 years of secondary school without the aid of qualified teachers and conventional laboratories. This ZIM-SCI study guide presents activities and experiments for a unit dealing with: (1) the generation of electricity; (2) uses of electricity in everyday life; and (3) safety precautions when using electricity in the home and in commerce and industry. Major areas investigated include: work and electrical power; changing electrical energy into other forms of energy; magnetic fields due to adjacement permanent magnets; the motor effect of an electric current; electromagnetic induction and generators; precautions related to using household electricity; and paying for electrical power. Information is provided throughout the unit to help students understand the concepts behind the activities and experiments. (JN)
